pub unsafe extern "C-unwind" fn VTFrameSiloCallBlockForEachSampleBuffer(

handler: &Block<dyn Fn(NonNull<CMSampleBuffer>) -> i32>,
) -> i32block2 and objc2-core-media and VTFrameSilo only.Expand description
Retrieves sample buffers from a VTFrameSilo object.
You call this function to retrieve sample buffers at the end of a multi-pass compression session.
Parameter timeRange: The decode time range of sample buffers to retrieve.
Pass kCMTimeRangeInvalid to retrieve all sample buffers from the VTFrameSilo.
Parameter handler: A block to be called, in decode order, with each sample buffer that was added.
To abort iteration early, return a nonzero status.
The VTFrameSilo may write sample buffers and data to the backing file between addition and retrieval;
do not expect to get identical object pointers back.
Returns: Returns kVTFrameSiloInvalidTimeRangeErr if any time ranges are non-numeric, overlap or are not in ascending order. Returns any nonzero status returned by the handler block.
